President Rodrigo Duterte said Friday that he hoped Moscow, a rival of the Philippines’ traditional ally the United States, would become his country’s ally and protector as he toured one of the two Russian warships on a four-day visit to Manila.

Duterte’s remarks came a day after Russia’s ambassador said his country was ready to supply the Philippines with sophisticated weapons and aims to become its close friend.

“We welcome our Russian friends. Anytime you want to dock here for anything, for play, for replenish supplies or maybe our ally to protect us,” said Duterte while shaking the hands of Rear Adm. Eduard Mikhailov, head of the Flotilla of the Russian Navy Pacific Fleet.

Duterte has thrown the future of Philippine-US relations into question with angry outbursts against the United States, a former colonial power, and some scaling back of military ties while taking steps to improve relationships with China and Russia.

He is due to go to Moscow in April. The visit by the Russian warships was the first official navy-to-navy contact between the two countries.

Last month, Duterte sent his foreign and defense ministers to Moscow to discuss arms deals after a US senator said he would block the sale of 26,000 assault rifles to the Philippines due to concern about a rising death toll in a war on drugs launched by Duterte.

Mikhailov said Tuesday that Russia wanted to hold maritime exercises with the Philippines to help combat terrorism and piracy.
